marnncnnrron OF WATER WIT RADIUM nix/[Anemone To all whom it may} concern:

Be it known that I, DICRAN H. KABAK-. JIAN, a citizenof the United States, and a resident of Lansdowne, in the county of Delaware and State of Pennsylvania, have when the main body of water is drawn off invented certain new and useful Improvements in the Impregnation of Water with Radium Emanations, of which the followingfis a specification.

' arious compounds and substances giving off 'radiuin emanations, useful for iinpregnating water, although supposed to be more or less insoluble are, in fact, soluble to such a degree that their permanent contact wlth water is productive. of waste and loss of radium. I

The'principal object of the present "invc'ntion is to avoid waste and loss of radium by solution in transferring radium emanations to water, or other appropriate liquid, to render it radio-active for therapeutieor other purposes. I

According to the present invention the water to be impregnated and the substance taining in its upper portion the substance or compound from which emanations reach the water through the confined air.

In the drawings, forming part. hereof, Figure 1, is an elevational view, principally in section, and

2, and 3, are respectively a central section and plane view of the underside of one of the elements shown in Fig. l, but- H drops'of liquid are quite firmly held their drawn to an enlarged scale.

In the drawings 1, IS a radium carrier. 0t

substantially inverted cup-shape,i or hell shape. 2, is a Substance, or compound giving off radium emanations, and itlis applicdto or arranged at the upper portion of the carrier. 3, is av vessel containing water wlncliis to be impregnated with-the radium einan ations and in which the carrier is immersed. Air confined in the carrier, as at a, Fig.- 2,. pre- "OlltSllllO, water from rising in thecarrier.- .l. high enough to contact with the substance through the confined air iu'ipreg'nate the water. Under these cinnlitions of separation it IS manifestly imposs ble to lose ra- Specifieation of Letters Patent.

of the carrier 1, may be's nallenough, for, example one-twenty-fifth of an inch, more or less, toretain a small drop of'water sufficientilfdact as Men for the confined air,

and before a new supply is added. When this is done the confined air impregnated with radium emanations is saved. To insure complete fillingof the'vessel 3, the l'atter may be provided. with a funnel 4, coininunicating. with. its interior by a Water intake 5, proper provision for air venting being made, as'by means of an upwardly ex-. tending air vent tube 6. The carriers 1, are shown as arranged in annular groups, ,depending from supports 7, which inturn are shown asvented at 8, inb rder to avoid trapping air. 9', isa guide rpdfor the supports 7, and it is shown as suspended flOIll the.

diuin by solution'inthe water. The borev bottom of the'funnel' 4, and if tubular its Y bottom is sealedto keep tirfout of it.

In use the vessel 3, is filled-by way of the funnel 4, with the liquid'to be impregnated,"

usually, though not exclusively, WaterQ The vent 6 perinits-offihe expulsion of all the air, except that confined, as at a, in the radium carriers 1, and this confined air keeps the liquid and substance 'or compound 2, out of contact, while permitting of the transfer of the emanations froui'one to the other: through it. The water having remained'in the vessel for asuflieient time for becoming radio-active, is drawn off at the tap or spigot 10, for use; and by repetition more supplies of water may be maderadioactive. When the Wateris drawn off and if thecarriers i, are of sufficiently small bore,

lower open ends and these drops serve to preventoroppose the escape of the confined air.

In describing ed claims I shall refer to the radium cariers as bein g'of inverted cupshape, intending. to cover equivalent shapes which operate by retaining air to keep Water from coming into contact with the compound and "still'permit of free diffusion of the'emanations through thecontined-airinix) the water.

What I claim is: 1. Apparatus for impregnating water with radium einai'iations comprising, incombination, a vessel adapted to be filled with water, a carrier impervious to liquids and gases inimerset in thewater, and an air seal the invention in the appendr separating the radium and the water, said seal enabling the emanations to diffuse into the Water.

2. Apparatus for nnpregnatmg a liquid with radium emanatlons comprising a receptavle for the liquid to be charged, a cup- 10 ranged to maintain the cup in a position with a layer of protective air trapped be tween the radium and the liquid.

7 3. The process of in'lpregnating Water with radium emanatlonswhlch consists in arrangmg the radium to present a max11num.ema-

nhting surface and causing theemunzxtions therefrom, to di-fi'use through a layer of protective gas maintained between said radium surface and the liquid to be impregnated.
